High-Temperature Processes for Sustainable H₂, NH₃, CO and CO₂ Production, Utilization and Storage

Dear Colleagues,

Following the premises of the Paris agreement (2016) and the recent Glasgow meeting COP26 (2021), the next few years are expected to pave the way toward decarbonization, experiencing a significant step forward to reduce CO₂ and other greenhouse gas emissions, increase the production of major chemicals (e.g., NH₃) via sustainable processes, and shift from fossil to alternative and renewable fuels (e.g., H₂). To support this trend, and to help the upcoming energy transition to a zero-net emission and no-carbon society, more fundamental and applied research is needed in these areas to intensify the reliability, feasibility, knowledge, and application of the currently available technologies, avoiding fossil fuel utilization and carbon emissions. For example, water electrolysis is a key enabling technology for the production of hydrogen for fuel, and high-temperature electrolysis in solid oxide cells offers various advantages such as efficiency, a higher rate of production, and non-precious catalysts; the valorization of CO₂ separated and captured from the atmosphere or industrial processes can be achieved with technologies such as high-temperature molten carbonate cells or CO₂-based power cycles. Nowadays, thanks to a multi-disciplinary approach in heat transfer intensification, electrochemistry, engineering, inorganic chemistry, and material science, there is a mounting vivacity and interest in these topics, and the result is the multiplication of possible configurations/combinations, engineered materials, and non-conventional systems for a wide variety of applications. On the other hand, there is still a long way to go to make these research results affordable for large industries in terms of investments, safety, and performances.

This Special Issue titled “High-Temperature Processes for Sustainable H₂, NH₃, CO and CO₂ Production, Utilization and Storage” aims to curate novel advances in the development and application of innovative and sustainable solutions for the production, utilization, and high-temperature storage of chemicals and fuels.

Topics include, but are not limited to:

• Biomass gasification;
• Water electrolysis;
• Methanation;
• Carbon capture and utilization;
• Chemical syntheses;
• Solid oxide fuel cell and electrolysis;
• CO₂ power cycles;
• Molten carbonate fuel cell and electrolysis;
• Sustainable ammonia;
• Renewable energy.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
